What Does IQ Mean?

IQ, or Intelligence Quotient, measures cognitive abilities, particularly fluid intelligence, which encompasses reasoning, learning, and pattern recognition. Historically, IQ scores were calculated as a ratio of mental age to chronological age, multiplied by 100. Today, IQ scores are standardized based on the average performance of a representative population.

How to Calculate It

To determine your IQ percentile, follow these steps:

  • Obtain Your IQ Score:
    • Take a standardized IQ test, such as:
      • Wechsler Adult Intelligence Scale (WAIS)
      • Stanford-Binet Intelligence Scale
      • Cattell Culture Fair Intelligence Test
    • Avoid online IQ tests that lack credibility and proper standardization.
  • Enter Your IQ Score:
    • Input your raw test score into the calculator.
  • Percentile Determination:
    • IQ scores follow a normal distribution (bell curve).
    • The calculator uses statistical data to determine the percentage of the population scoring at or below your IQ.

What Is a Healthy Percentile?

Healthy or Average Percentile:

  • A score between the 50th and 68th percentile corresponds to an IQ score of 85–115.
  • This range is considered normal and reflects average intelligence, covering about 68% of the population.

High Percentile:

  • Percentiles above 84th are associated with scores of 116 and higher, indicating above-average intelligence. For example:
    • 95th percentile: IQ of 125 (Top 5% of the population).
    • 99th percentile: IQ of 135 (Top 1% of the population).

Low Percentile:

  • Percentiles below 16th are associated with scores under 85, reflecting below-average intelligence.

Understanding your percentile provides context for your IQ score and allows you to see how you compare to the general population.
